Abstract
A gas block assembly may include a gas block including a gas port to receive gas provided by a gas port of a barrel; a tapered fastener opening; and a tapered fastener insertable in the tapered fastener opening, the tapered fastener including: a length further including a tapered section to contact a sidewall that defines the tapered fastener opening; and means for rotationally driving the tapered fastener into the tapered fastener opening. In other embodiments, an adjustable gas block includes sealing ring(s) on a groove in a rotationally actuated gas metering shaft.
Claims15
A barrel assembly for a firearm, the barrel assembly comprising:
- a barrel having a gas port and a taper interface, wherein the taper interface includes one or more sloped surfaces defined by part of an exterior of the barrel;
- a gas block around the barrel;
- and
- the gas block including a timing system including an opening and a tapered fastener insertable in the opening, the timing system configured to rotationally orient the gas block to position an ingress port of the gas block over the gas port, wherein the tapered fastener includes:
- a length including a first tapered region arranged to lockup with the one or more sloped surfaces of the taper interface of the barrel, wherein the tapered fastener is configured to move along the taper interface and bias against the one or more sloped surfaces and the gas block to create the lockup;
- and
- the length further including a second region to interface with the gas block;
- and
- a drive mechanism for rotationally driving the tapered fastener into the opening.
A gas block assembly, comprising:
- a gas block including a gas port to receive gas provided by a gas port of a barrel;
- a tapered fastener including:
- a length further including a tapered section configured to lockup with a taper interface defined by the barrel, wherein the taper interface includes one or more sloped surfaces defined by part of an exterior of the barrel, and wherein the tapered fastener is configured to move along the taper interface and bias against the one or more sloped surfaces and the gas block to create the lockup;
- and
- a drive mechanism for rotationally driving the tapered fastener into an opening.
An apparatus, comprising:
- an adjustable gas block including:
- an ingress port to receive gas expelled from a gas port located on a barrel;
- and
- a rotationally actuated gas metering shaft drivable in a threaded section of a bore of the adjustable gas block to at least partially cover the ingress port with the gas metering shaft to restrict a flow of the gas, wherein the gas metering shaft includes a section to form a seal with a smooth section of the bore in a range of selectable positions of the gas metering shaft from maximum gas flow restriction to minimum gas flow restriction, the section of the gas metering shaft including a groove and a gas seal located in the groove;
- wherein the bore is continuous such that the smooth section directly transitions to the threaded section;
- wherein, when the gas metering shaft is rotated in the threaded section, the seal of the gas seal is maintained until the gas seal reaches the threaded section is reached.
